To all whom it may concern:

Be it known that I, SAMUEL H. @nnrmrr, a citizen of the United States,residing 1n the borough of Brooklymin the city and State of New York,have invented new and body portion closed at one end, with a coveradapted to be slipped tightly over the open end, which are convenientlyreferred to as slip-cover cans. Such receptacles are used for thedistribution of products which re quire a considerable degree ofprotection from the atmosphere and must be repeatedly and easilyavailable but which do not command a high price, so that the receptaclemust possess the characteristics of being tight, easily opened andclosed, and cheap.

For example, in the. caseof baking powder,

the quality and eflicacy of the product when it reaches the consumerdepends to a considerable extent upon the degree to which the contentsare preserved from the action of dampness in the air, the receptaclecontaining the powder must be frequently opened and closed as thecontents are gradually used, and'the price of the article is such thatthe receptacle'in which i it is distributed must lie cheap.

Heretofore packages for goods of this 1 character have commonly.consisted of a 4 round receptacle having one end closed with a coverfitting down snugly over the open end thereof. The receptacle hasusually been made of metal. Paperboard and the like, though cheaper,have been used only to a comparatively inconsiderable extent chiefly byreason of the difiiculty of securing a sufliciently tight contactbetween the body portion and cover of the receptacle to protect thecontents from the action of the atmosphere. It is one of the objects ofthis invention to remove that difiiculty by a simple expedient so thatmaterials cheaper than metal may be used advantageously in suchreceptacles.

'Whatever the material, receptacles of this character have heretoforebeen defective and objectionable and involve losses and inconveniencesto the manufacturer and consumer,

which it is the object of this inventionfto remedy. For example, in theeffort to increase the protection of the contents of such receptaclesand otherwise, it is customary to cover the receptacle, and particularlythe point Where-the edge of the cover meets the body, by a label. Thenature of such receptacles has heretofore been such that there has beenno adequate protection for the label, with the result that in shipmentthe labels are rubbed and disfigured to such an entent as to render manypackages unsalable unless each package is packed in chad, corrugatedpaper or other protecting material, which involves considerablyincreased expense. This defect has been augmented by the fact that thejoint between the side and bottom of such receptacles has project .edout from the plane of the side, so that rolling, thus impeding thesuccessful operation of the method commonly practised in transportingthe packages from one part or department of the factory to another inthe process of preparation of such products for the market by rollingthem on their sides,

and those connected with the fact that the receptacle does not lie levelon its side in the labeling machines, thus interfering With the accuratemechanical labeling of such receptacles (which, as a commercial matter,is almost a necessity), a difficulty greatly increased by the fact thatthere has been no guide for the label at the top of such receptacles.

In order to make such packages serve their purpose of protecting thecontents from the atmosphere, it has been essential to make thecover fitthe body portion so tightly that its removal has been a matter of greatinconvenience and difiiculty, there being nothing on the cover to takehold of, and this defect has been the more objectionable because thecovers must be repeatedly rethe like.

ter, as, for example, in making biscuits and The objects of thisinvention are to do away with these defects and objectionsv and at thesame time secure many advantages without increasing the cost of thereceptacle.

With these and other objects in view, the invention comprises forming onthe side of the cover at or near its top a bead or ridge projecting outfrom the plane of its side,

, preferably stamped in the cover itself, without seams or solder andwithout separate material, this bead or ridge serving to protect thelabel in shipment and thus enable the packages to be shipped withoutprotecting material, making the receptacles straightrolling andlevel-lying in the labeling machine, serving as a gulde at the top forthe label, and affording a grip for removing the cover so that the covermay be made considerably tighter, and thus the value of the receptaclefor its purpose increased and the cover at the same time moreconveniently removed and used as a cutter. Moreover, in the case ofreceptacles of the kind having a paperboard body, by making a slightridge at the top of the body which, when the cover is put on, is firstcompressed and then expands into the cove constituting the in.- ner sideof the ridge on the cover, the air and dampness are kept excluded and'the cover held secure and yet readily removable, thus enabling.such'materials tobe used in place of metal in such receptacles.

In the accompanying drawing, Figure 1 is I a view of three of suchreceptacles placed side by side, as for shipment. Fig.2 is a side view,artly in section, of such a receptacle, and ig. 3 a top view, of thecover.

The receptacle consists of the body portion 1 made up of the side 2 andbottom 3,

the joint between the side and bottom form ing the projection 4, and thecover 5 fitting tightly over the body portion. Said cover has at or nearits top a ridge or bead 6 extending out from the plane of its side asulficient distance to prevent the side of the cover or body portioncoming in contact with any straight, or approximately straight, surfacev as long as the receptacle. The inside of this bead or ridge ispreferably in the form of a groove, particularly when the coveris to beused in connection with a corresponding ridge .on the body portion,especially when such portion ismade of non-metallic mate-.

I rial, as paperboard, or the like. The advanta'ges of such a ridge onthe cover in shipment are illustrated in Fig. 1, an inspection of whichwill make it apparent that by reason of such ridge on the cover with thepro- I as jectingjoint at the bottom of the body portion suchrece'ptaclesmay be shipped in cases or boxes adapted to hold a number ofthem without the labeds being injured or disfigured and without the useof chaflf, corrugated paper or other protecting material.

The advantages to which I have referred,

and particularly those connected with the practicability of making theslip-cover fit the body portion more tightly and thus increase theprotection of the contents, while at the same time being strengthenedand far more easily removable without adding. materially to the cost,are apparent and will be fully appreciated by those familiar with slip-1cover receptacles.

It is to be noted that this invention relates to the improvement ofslip-cover receptacles, Which present to the manufacturer of articlesnecessitating their use and to the con-' sumer of such articlesjproblems distinct from those connected with receptacles closed in morepermanent fashion, as by solder, folding joints, or the like. .7
